Leviticus 23:43

That your generations may know that I made the children ofIsrael to dwell in booths Which by the providence of God the Israelites were obliged to make for themselves to dwell in: when I brought them out of the land of Egypt; for the very first place they came to, when they departed from thence, was called Succoth, from the booths they there built: I [am] the Lord your God; who brought them out of Egypt, made them to dwell in booths in the wilderness, and enjoined them the observance of the feast of tabernacles in memory of it, in which he expected to be obeyed.
